The Oakland City Council moved closer on Tuesday to banning hammers, wrenches, shields, sling shots, paint projectiles and other “tools of violence and vandalism” at protests, raising concerns by the American Civil Liberties Union and local activists.

“I appreciate that the City Council wants to make demonstrations safe,” ACLU attorney Michael Risher told KGO-TV. “But they should look at both sides of the equation and realize that there are more protesters who are injured by the police during protests than there are officers who are injured by protesters.”

The council voted 5-0 in support of a law that will make it a misdemeanor to bring destructive items to demonstrations, the Oakland Tribune reported.
